To @ZZ 107mm t may concern' Be it known that FRANK PARIZEK, a citizen ofthe United States, residing at Chicago, in the county of Cook and Stateof Illinois, have invented a certain new and useful Improvement in Capsfor Gasoline or Similar Receptacleaof whichthe following isa full.clear, concise," and exact description7 reference being had totheaccompanying drawings, forming` a part' of inthe tank through thevent due .to splash ing' ot the liquid because of movements of the tank.or from` any other cause.

It is still a further purpose of the invention to provide a screw cap ofthe character described above that has screwthreaded engagement with thetank upon which it is mounted and which is provided with 'circuitouspassages to establish communication between the tank and the outerfair.The cap is preferably provided with a cross rib on the top thereof thatis hollow land which is separated from the hollow body portion ot.' thecap by a partition provided with openings communicating` with the spacein the body portion and the hollow of the rib, and provided with anopening in a wall of the rib communicating with the outside air and withthe space within the rib.

It is also an object Aof the invention to provide a cap of the characterdescribed above with passages connectingV the space within the rilI withthe space 'within-*the cap that extend at an oblique angle to thevertical so that any liquid that may be splashed into the chamber in therib will readily flow down the walls of said passages into thereceptacle to which the cap is attached.

Other objects and advantages oit the invention will appear as thedescription or"V the accompanying drawings 4'showing` one form that theinvention may take proceeds. However, I desire to have it distinctlyunderstood that I do not intend to Vlimit Vmyself to the enact detailsshown and described but that I intend to include as part of myinventionfa'll such obviouschanges and modilications'fof parts as would-occur' 'to a person skilled in this'vart and 'as'woul'd fall withinythe scope o ithe, claims.

' 3 is la side elevation'ofaslightly inodiiedform." 'i f h Referring indetailto the drawingsthe. limproved 'capf comprises a cylindrical'body 4portion 4l"whichis 'shown #as being 'in- Aternally fscrewthreaded at 5but which may be s crewthreaded either externally or are improved is a'vertical section thereof; Vand internally,I asis common wi'tlicaps ofthis .'cliaracte'r, hdepending', upon the manner in which thereceptacleupon which the cap is used is threaded. the 'capU being shown as beingHexternally screwthreaded at`- 5 in Fig'.

vpurpose to provide a cap of thefgfeneral` character' outlined that isprovidedvvith`v y The said cap islprovided with a .closed end portion 6as isl customary and is provided 'with a' transverse rib 7,' which 'so ivent openings so as tol permit air t-oenter f the tank and'y break yanyvacuum that might occur therein due to emptying' of? the same 'i y'andthus permit the flow of liquid from,

the same to continue without interruption due to this cause. Capshave'been "ordi-` narily provided withl vent l holes that merelyextended through the closed end of the cap 4and through which the liquidin the tank quite often .leaked upon agitation ot' the liquid kin thetank from any cause,'- such asflor instance, in the'case wherefthe tankis mounted'on a vehicle, theagitation or the liquid` due to movement .ofthe ve-f" i i hicle, 'In order to yavoid this objection to `thevent.openings in a cap the` particular construction of cap used yin thepresent device has been developed. ln' the present ioo device the rib isprovided with a space 'S within the same and this spaceis sepa-A ratedfrom the space within the cylindrical portion of thecap by means of `apartition- 9, the Vpartition 9 being' formed in part in#r tegral withlthe vbody portion ofthe cap-4, and the opening' remaining in the jsamebe-y ing closed by means of theL plate A10, it-being necessary to `makethe'l device/fin this manner as the castingcould lnot be made with acomplete partition'betweenthejrib iio and the body portion. of the capWithout providing an opening somewhere in the rib or cap to permit theremoval of the core used in making the mould for the casting.

.It is preferred to leave this opening in the partition and close itwith the plate l0 as this would leave the external surfaces of the capand rib a smooth casting with no breaks therein. The edges of thepartition 9 adjacent the opening therein are provided with oii'setportions 14;, and the edges of the plate l() are forced into engagementtherewith so as to assume a shape corresponding thereto, to itirmly holdsaid plate lO in place. lt will be noted that the partition 9 is archedso as to follow substantially the same curvature as the outer surfaceor' the cap so that any liquid that might collect in the chamber 8 willflow down the curved surface of the partition 'to theouter lowermostedge portions thereof. The partition 9 between the rib and body portionof the cap is provided with a plurality of passages l1 which preferablyextend at an oblique angle to the axis of the cap, and the upper wall ofthe rib 7 is provided with a passage l2 leading to the outer air.

rlhe passages ll are placed at an oblique .angle as shown in Fig. 2 sothat it any liquid is splashed up into the same it will readily run downthe lower oblique wall o1"- the passage into the tank and will thus aidin preventing clogging of the openings by means of drops of the liquid.The openings ll are located adjacent the outer edge ot the partition sothat any liquid in the chamber 8 will flow into the same and down the.walls thereof into the receptacle upon which the cap is secured..

It will be seen that in this manner a circuitous passage is providedttor the passage of air from the outside ot the tank to the interiorthereof through the opening l2, space 8, and through the openings ll.Due to this structure the liquid it splashed up against the cap will notpassv beyond the space 8 under any circumstances, and will in l ordinarycircumstances not pass beyond the passages il, and it will thus be seenthat there will be very little possibility that any ol the liquidwillibe splashed out through the opening l2. The cap is provided with aconvexed outer surface i3 so as to vgive the caps a better appearanceand the rib 7 is preferably curved at 14 on substantially the sameradius as the cap.

- Having thus described my invention `what I desire to claim and secureby U. S. Letters Patent is:

l. A ycap of the character described comprising a cylindrical side wallportion screwthreaded for a portion or' its length, and a `closed endportion providing a hollow cross rib, said end portion being providedwith a circuitous passage providing a vent for said cap.

2. A cap of the character described comprising a cylindrical side wallportion screwthreaded for a. portion of its length, and a closed endportion, said end portion being provided with a double walled portiondefining a space between said walls, and passages through both saidwalls, certain of said passages being inclined to the axis of the cap toallow the liquid to run down the walls thereof, and prevent cloggingofsaid passages by drops of said liquid.

A cap of the character described coinprising a cylindrical side wallportion screwthreaded for a portion of its length,'and a closed endportion, said closed end portion being provided with an externaltransverse hollow rib, forming al chamber within the end wall of saidcap, and said cap being provided with passages extending through -onewall oit said chamber' to the inside et said cap and through anotherwall or" said chamber to the outside of said cap.

4l. A cap of the character described comprising a cylindrical side wallportion screwthreaded for a portion of its length, and a closed endportion, said closed end portion being provided with an externaltransverse hollow rib, Jforming a chamber within the end wall of saidcap, and said cap being provided with passages extending through onewall ofi said chamber to the inside oi sait cap and through another wallvoit said chamber to the outside ot' said cap, the passages in saidwalls being out ot alignment.

5. A cap of the character described comprising a cylindrical side wallportion screwthreaded for a portion of its length, and a closed endportion, said closed end portion being provided with an externaltransverse hollow rib, forming a chamber within the end wall orp saidcap, and said cap being provided with passages extending through onewall of said chamber to the inside ot said cap and through another wallot said chainber to the outside otl said cap. certain ot said passagesbeing inclined to the axis ot said cap.

6. A cap of the character described comprising` a cylindrical side wallportion screwthreaded ,'r'or a portion ot its length, and a closed endportion, said end portion being provided with a double walled portiondei'iniug a space between said walls, one ci" said walls being archedupwardly, and passages through both said walls, the passages throughsaid arched wall extending obliquely from the lowest part oi" said archto drain said space between said. walls whereby clogging of saidpassages by drops oi" liquid is prevented.
